7.1 Project Navigator - When an XPS project is added as a submodule in ISE, the" _bd.bmm" file is not generated, and bitstream contains no software

Description

Keywords: Project Navigator, EDK, BMM, Export, bitstream, ISE

Urgency: Standard

General Description:When an XPS project is added as a submodule to an ISE project, the XMP top instance name is locked to <xmpname>_i. If the XPS system is instantiated using a different instance name in the ISE top-level design, Project Navigator should update the BMM under any condition. If the instance name in the top-level design is different, the Generate Programming File process does not recognize the underlying BRAM instances, resulting in:

1. <xmpname>_bd.bmm is not generated.2. XPS Library Generation is not run.3. The bitstream contains no software.4. Running the Update Bitstream process in ISE produces a header in the transcript with no warning, no done indicator, and no status icon in the process tree.

Solution

To work around this issue, always name the embedded instance "<xmpname>_i".
